- specification.

This invention has reference to improvements 1n 'apparatus for cokeovens, and is designed more particularly for facilitating the removal ofthe coked charge from the oven and the deposition thereof into cars orother suitable receptacles.

In'large coke oven plants, the ovens are arranged in a long series., andusually have immediately adjacent to them car tracks for the readydeposition -of the coke, when remove'd from the ovens, into freightycars for transportation to distant oints.

I have devised means w 'ch form the subject matter of anotherapplication for Letters- Patent,whereby the entire contents of a cokeoven after the coking operations have been completed is pushed out atone operation from the ovens, so that the coked mass is maintained in aslarge lumps as ossible for reasons which need not be set fort herein.

The presentl invention relates more particularly to means whereby theconveying of these largemasses of coke from the ovens to cars is greatlyfacilitated and the invention comprises a conveyer structure mountedupon Ia truck movable upon tracks immediatel adjacent to the series ofcoke ovens, and this conveyer is constructed to receive the entirecharge of` the coke oven at one time and to convey such amount thereofas may not be readil contained upon the conveyer into a gon ola car.constructed to operate with either` a high or low type of cars, and maybe moved from oven to oven in order, and `co-acts with a suitablemechanism adapted to pushthe coked charge at one operation from theoven. The structure of the conveyer is such that it may receive thecharge directly from the oven and permit a portion thereof to fall intoa suitably `placed car, then when moved to the next oven, receive thenext charge which underI the action of the pushin mechanism at the frontend ofthe Oven Wi 1 push that portion of the coke remaining on theconveyer into the car and the newly ejected charge will replace the oneirst pushed out upon the conveyer.

and, also, s

'present invention, but is made The conveyer isl p matter lof anotherapplica-hon, and need not.

In order to faciiitate the passage of the heavy mass .of coke over theconveyer, an endless conveyer structure may be used, and further, inorder to prevent the conveying of coke dust and such matters to thecars, a part .of the bottom of the conveyer, either adjacent tothe exitopening of the oven, 'or at any other suitable int in the length of theconveyer, may be fimed with a suitable screen through which ineparticles will gravitate into a receptacle from which they may beremoved from time to time.

rThe invention will be best understood on reference to the accompanyingdrawin drawings,.-

Figure 1 is a longitudinal section through a coke oven showing theconveyer in lace at the exit end of the oven, and the pus 'ng apparatusin place at the front end of the oven,

owing la car In position to receive the coke. Fig. 2 is a longitudinalsection through the conveyer, showing it in position for depositing cokein a deep gondola car, and Fig. 8 is a similar view showing the con`veyer in position to deposit coke in a shallow gondola car or box car.

Similar numerals of reference are employed to indicate correspondingarts throughout the several igures of the w1 ings. s.

Referring to the drawings, there is shown a coke oven, which may be ofreferred type, and is of suitable shape and Ilength, but in itselfforming no part of the present invention; this coke oven is 'broken intwo and only the ends are illustrated. 0n one side of the oventhereisshown a pushing a paratus2, which in itself forms no art o the bespecially describe further than to state' that it isprovided with aushing head 3 and a telescoping carrier t enefor, so arranged as toenter and pass entirelv through Athe coke oven to push or force thecharge after the coking operation is finished out subject through theother end opening 4 of the oven.

Within a suitable distance of the exit end of the oven series, it beingunderstood that these coke ovens are arranged in 'a series of manyovens, there is arranged a track 5 parallel with the series of ovens andwithin suitable proximity thereto. This track is u on an elevation orplateau 6, at the end o which is located another track 7 connected withsome railway system and designed for the reception of suitable cars 8,which may be of the` gondola or box type.

The track 5 is adapted to receive a truck 9 upon which is formed asuper-structure 10, designed to receive a conve er 11, which latter mayhave its outer en that is the end remote from the oven, somewhat higherthan the oven end. The conveyer structure may be similar to ordinaryconveyers, thatl is,'1t comprises a bottom 12 withI spaced side members13, so that when the lower end of the conveyer is in coincidence withthe floor of the oven and o posite the exit opening 4, then the chargeci) coke forced out from the oven under the im ulse of the pushingapparatus-2 is receive upon the conveyer and travels along the same1until ultimately it drops off of the end of the conveyer into the car 8.1n order` to adapt the conveyer to, cars of different heights, thedischarge end may be formed of a section 14 hinged to the main (portionof the conveyer, as shown at 15, an any suitable means, for holding thishinged end 14 in position and adjusting the same, may be utihzed. In thedrawings this is conventionally shown as a latch link 16 hin ed to abracket 17 fast onI the section 14 an having its free end formed into atooth 18 arranged to engage against any one of a number of teeth 19 faston the under side of the bottom of the` conveyer 11. By this means thefree end of the conveyer ma be maintainedv in line with the main bo y ofthe conveyer, or may be tilted downwardly, as shown in Fig. 3, so as tobring the discharge end of the conveyer close to a low gondola or boxcar, and then Ythe heavy masses of coke will fall but a comparativelyshort distance before reaching the car. e

There is a liability of there being in the mass of coke material more orless coke dust or dirt, or ashes, and in order to revent this from beingcarried to the car, t e bottom ofthe conveyer at the end immediatelyadjacent to the discharge end of the oven, as indicated in the drawings,or some other art-of the conveyer, if so desired, may be ormed withslots, as shown at 20 too small to permit the coke falling through them,but allowing the dust and dirt to readily gravitate from the conveyer.`To prevent the dust and dirt lso extracted from the -mass of coke fromaccumulating alon the track 5, the :conveyer may be provi ed with acompartment 21de endent from said conveyer coincident wlth the slots orgrating 20, and this compartment may be normally closed at each end byra door 22, so that its contents may be readily removable at' will. Itisof advantage to reduce the frictional engagement of the coke with thebottom of conveyer as much as may be, and for this purpose the conveyermay be provided immediatel above its bottom section 12 with an en essbelt 23 of any suitable type, say with endless chain supports at the twoedges, assing over rollers 24 and returning beneath the floor 12, thebelt being suported at each end upon suitable drums 25.

his belt need extend only through the main body of the conveyer, andwill practically eliminate the friction between the coke and I thebottom of theconveyer.

When a charge has been forced out of an oven, the material portionthereof will remain upon the conveyer, and only a comparativel smallportion of the first charge will pass om the end 14 into the car 8. Thesecond charge, however, will force the remainder of the first chargefrom the conveyer, and a certain portion of the second charge -willalso, fall into the car. Of course, under these conditions the truck 9is moved from one coke oven to the next, and the car or cars 8 areappropriately moved until the car is filled, provided each car 8 is toolarge to be filled by a single oven charge. When the ovens are largeenough to contain each a charge sufficient to fill a car, then the carsmay remain stationary, while the conveyer is moved from oven to oven.

What is claimed is 1. In an apparatus for coke ovens, a con' v eyer bodymounted upon a truck, a fixed grate in the bottom of the conveyer body,a refuse receptacle carried by the conve er body beneath the grating,and a free en ess belt extending lengthwise of the bod between thegrating and the end of said ody.
